ServiceNow (NOW-2.9%) slides as H-P (HPQ) introduces cloud-based IT service desk software with fairly aggressive pricing - $89/month for dedicated users, $178/month for a "floating" account that's shared between users. H-P's pricing suggests a willingness to cannibalize sales as of its traditional Service Manager software in order to stem the share gains of ServiceNow and other cloud-based rivals. Citrix (CTXS) entered this market last month by acquiring startup Beetil.
